Unit Test Friendly way of using membership details inside the controller

Here is a piece of code from one of the controller inside my ASP.NET MVC 3 App :

_destinationdetailRepository.Add(new DestinationDetail { 

    DestinationID = destination.DestinationID,
    CreatedOn = DateTime.Now,
    CreatedBy = User.Identity.Name
});

What is important here is the CreatedBy property value which is User.Identity.Name. It works great and I use this on another parts of my app as well. But, I guess this is not a unit test firendly way of doing things.

So, what is the way of using Membership data inside the controller so that I will be happy when I am unit testing m开发者_运维百科y app.

No, it's unit test friendly and it is correct code. The User property is an IPrincipal interface that can be mocked in an unit test.
